Benefits of technology

[0009]In one embodiment of the patent invention, a separate flexible sleeve of polymeric material having a relatively low coefficient of friction as compared to the surface of the floating cable is provided and installed to surround substantially the entire length of the portion of the cable that floats on the water's surface. The sleeve is sufficiently flexible to permit the natural movement of the buoyant cable. When a loop is formed i

Embodiment Construction

[0028]A first embodiment of the present invention will be described with reference to FIGS. 1-5. Referring to FIG. 1, a power cable 20 is shown which electrically connects a power supply 10 to a pool cleaner 50. The pool cleaner 50 is a robotic self-propelled pool cleaner that is submerged in the pool water 40 and traverses the bottom surface in a pre-programmed and / or random pattern. In one embodiment, a transformer 11 can provide intermediate connection from the power supply 10 to the power cable 20.

[0029]The power cable 20 generally includes a buoyant material which causes a portion of the power cable 20 to float on the surface 41 of the water 40. However, its attachment to the submerged pool cleaner 50 causes a portion of the power cable to become submerged starting, e.g., at a location 42 along the power cable 20 which is dependent on the depth of the pool cleaner 50 below the surface.

[0030]Typically, pool cleaners or at least their associated power cables are removed from the ...

Abstract

A buoyant power cable for electrically connecting a submerged robotic self-propelled pool cleaner to an external power supply that is subject to foaming coils in the floating portion that are not readily opened and interfere with the desired movement of the pool cleaner is provided with a separate flexible sleeve of polymeric material or an extruded coating of a foamable or solid polymeric composition having a relatively low coefficient of friction as compared to the surface of the floating cable over the portion of the cable that floats on the water's surface so that when one or more loops are formed in a portion of the cable covered by the sleeve or coating, the contacting surfaces easily slide over each other to permit the removal of the loops and the free movement of the pool cleaner.

Description

RELATED APPLICATIONS[0001]NoneFIELD OF THE INVENTION[0002]The invention relates to floating power cables used with robotic self-propelled pool cleaners.BACKGROUND OF THE INVENTION[0003]Robotic swimming pool cleaners receive electrical energy from a remote power source that is external to the pool through a buoyant or floating power cable. The electrical conductors are encased in a foamed rubber or other polymeric composition that renders the assembly buoyant. As the pool cleaner traverses the bottom surface in a pre-programmed and / or random pattern, the portion of the cable that is floating on the surface of the water can form loops. At the point of contact between the opposing surfaces of the cable, the coefficient of friction is sufficiently high to preclude sliding movement, even though the area of contact is relatively small. As a number of loops are formed, the tendency of the power cable to restrict the movement of the submerged pool cleaner increases to the extent that it int...
